MODCK[1-3]
MODCK_H-
table entry guarantees only the required minimum CPU operating frequency. The “high” values are for the purpose
of illustration only. Users must select a mode and input bus frequency so that the resulting configuration does not
exceed the frequency rating of the user’s device. The minimum CPU frequency is 150 MHz for commercial
temperature devices and 175 MHz for extended temperature devices. The minimum CPM frequency is 120 MHz.
MODCK[1-3] = three hardware configuration pins.
The “low” values are the minimum allowable frequencies for a given clock mode. The minimum bus frequency in a
PCI_MODCK determines the PCI clock frequency range. Refer to
MODCK_H = hard reset configuration word [28–31] (refer to Section 5.4 in the MPC8260 User’s Manual ).
CPM multiplication factor = CPM clock/bus clock
CPU multiplication factor = Core PLL multiplication factor
